To build a utility-scale solar plant 1], you must budget approximately $800,000 to $1,200,000 per megawatt (MW) of installed capacity. The total cost is dominated by the solar panels, inverters, mounting systems, and grid connection fees.
[pdf] The container battery utilizes 700-Ah lithium iron phosphate (LiFePO4) cells in a liquid-cooled 1,500 to 2,000-volt configuration. Despite its massive 8-MWh capacity, the system can fit into half a standard shipping container, weighing approximately 55 tons (50 tonnes).
